Data transfer to a mesh with different topology
I was able to get a uv transfer using the the Data Transfer Modifier.
Select object to transfer the UVs to, add the Data Transfer Modifier
In the source parameter select the model to get the uvs from, check on Face Corner Data.
In Face Corner Data check on UVs. In the mapping parameter select Nearest Face Interpolated.
Also, clicking off the Object Transform button next to the Source parameter is great if your source object has been moved away from your destination object.
